Shizzell, I hived a package in the drizzle last week...the guy I got the bees from said they were in the crate for a while now and should be hived asap (he said a week...I don't know if I believe that). I had a helper, no umbrella and took out five frames, put the queen in place and pushed her off to one side and put the whole crate in the hive with the opening facing up. Closed her up til the following day and then I set it up properly. The bees were fine.
If I had another deep I would have place that on top and rested the crate on top of the frames on its side (with it open of course).
The queen is now laying and the hive is happy.
